22 June 2015/Kiel. In addition to carbon
dioxide there are plenty of other greenhouse gases. Nitrous
oxide is one of them. However, a global assessment of
emissions from the oceans is difficult because the measurement
methods used so far have only allowed rough estimates. Using a
new technology for continuous measurements, researchers of the
GEOMAR Helmholtz Centre for Ocean Research Kiel and the
Christian-Albrechts-Universität zu Kiel have now discovered
that nitrous oxide emissions from the Southeast Pacific are
much higher than previously thought. They publish their data
in the international journal Nature
Gesoscience.

MEMENTO is
an initiative started in 2009 that aims to collect available oceanic and
atmospheric methane and nitrous oxide data into a global database for the
computation of global concentration and flux fields. Data from about 180
campaigns with more than 100,000 nitrous oxide and 20,000 methane measurements
have been collected. All data included in MEMENTO have undergone a first order
quality control on the availability and range of essential and ancilliary data
and their metainformation before they are imported into the database.
Interested users are invited to download the data through our data portal which
is accessible via the MEMENTO webpage (https://memento.geomar.de). We are furthermore looking for additional data contributions to
expand our dataset.

November 11, 2014/Kiel. Ocean acidification might alter climate-relevant functions of the oceans’ uppermost layer, according to a study by a group of marine scientists published in the “Journal of Geophysical Research: Oceans”. In an experiment led by GEOMAR Helmholtz Centre for Ocean Research Kiel, the researchers observed a close coupling between biological processes in the seawater and the chemistry of the sea surface microlayer. Also, they noted a growing number of specialised bacterial and algal cells in this microenvironment. These changes might influence interactions between the ocean and the atmosphere such as the air-sea gas exchange and the emission of sea-spray aerosols that can scatter solar radiation or contribute to the formation of clouds.

Mesocosm experiment on the effects of ocean acidification at its summit

29.
October, 2014/ Kiel, Taliarte. In a long-term field study led by GEOMAR
Helmholtz Centre for Ocean Research Kiel, an international team of
scientists investigates the effects of ocean acidification on pelagic
ecosystems in the subtropical Atlantic. The field experiment with the
KOSMOS mesocosms off Gran Canary now culminates in the simulation of
deep-water upwelling – an event that can boost productivity in these
nutrient-starving waters. For this purpose, the researchers developed an
80,000 litres deep-water collector.

On October 6, several groups from the SOPRAN project met in Heidelberg to discuss the measuring program of the final SOPRAN laboratory experiment at the Heidelberg Small-Scale Air-Sea Interaction Facility, the Aeolotron.

The focus will be on the first air-sea gas exchange measurements with seawater from the Atlantic Ocean in the Aeolotron, including the effects of the natural surface micro layer and bubbles. In addition, aerosols will be sampled with different techniques to investigate to what extent organic material from the sea surface micro layer (SML) is carried into aerosol. The experiments will also be essential for the provide further experimental data for the new SOPRAN air-sea gas transfer model with conditions, where data are not yet available.

The participating groups are J. Williams, MPI for Chemistry, Mainz (PTR-MS measurements of gas concentrations in air and water), A. Engel, GEOMAR Helmholtz Centre for Ocean Research Kiel (SML measurements), M. van Pinxteren, TROPOS (aerosol measurements), and B. Jähne, U. Heidelberg (MIMS and FTIR gas exchange measurements, active and passive thermography, and all environmental parameters including wave slope imaging). External groups include O. Wurl, ICBM (CO2 gas exchange and SML measurements), B. Schneider, IOW (CO2 measurements), and foreign groups from England (J. Najera, U. Manchester) and France (B. D'Anna, CNRS, lab IRCELYON). The latter two groups will support the aerosol measurements. The experiment will take place from November 3 until 28, 2014. On September 23, twenty tonnes of Atlantic seawater, sampled from the Northern Atlantic Ocean on board of the research vessel POSEIDON and reloaded to a road tanker at GEOMAR, arrived in Heidelberg and were filled into the storage tanks in the basement of the building, where the Aeolotron is located.

A mesocosm experiment was conducted to investigate the impact of rising
atmospheric CO2 on the build-up and decline of organic matter during
coastal phytoplankton blooms. Five mesocosms (each with a volume of 38
m3) were deployed in the Eckernfoerde Bay close to the site of the Time
Series Station Boknis Eck in Spring 2009. The results of the experiment
have been recently published by Anja Engel and colleagues in a Featured Article of 'Journal of Plankton Research'. The download of the article (J. Plankton Res. vol. 36, pp. 641-657, 2014) is free.The mesocosm experiment was supported by the SOPRAN project.
